904 with Turbo Action shift kit, no 3rd

This has been a long time coming, but after many other projects come and gone, I decided I better pull the Scamp back out and fix this old transmission problem. I think I finally found the problem, but I wanted to go over it with people who have much more experience (you guys). So,

After adjusting the throttle pressure on the valve body with a custom tool, I hooked the pressure gauge onto the line pressure port on the 904. In "D," wheels off the ground, PSI begins to show at about 30mph --> It jumps to about 50psi/30mph/1000rpm. With throttle lever pulled all the way, it increases to 86psi. Here are some other readings I got: 72psi/37mph/92psi(w throttle pulled), 64psi/40mph/90psi(w throttle pulled), 70psi/50mph/94psi(w throttle pulled), then it went back to 40psi/33mph at idle-900rpm and 86psi with throttle pulled back.

My FSM says kickdown release pressures should match the Line pressure readings. I plugged into the kickdown servo release port (front port on the passenger side). I got zero psi, no matter what RPM/MPH I was at. I raised it to 5000rpm and had zero psi on the gauge. FSM says this could be caused by front servo leakage, or front clutch leakage. My problem is "no 3rd gear." This was a brand new rebuild (years ago) and I swear I already pulled it back out a 2nd time to fix this problem. I am wondering if you guys can throw me some insight, if there is no other possibility but excess front clutch leakage. I swear I did a air test before installing it last time. This sucks, but I need to get this car back on the road.

My GOV pressures: 30mph-4psi, 40mph-20psi, 45mph-35psi, 50mph-48psi, 60mph-55psi. They seem to be in spec, though I doubt my speedo is accurate seeing that it sticks at 25mph.

Do you guys also think this points to front clutch leakage? I have found excess clutch mud in the pan on several occasions. Reverse is fine as always. Please let me know what u think.
